Still not ready for release but here is the experamental code I'm using to enable CommentLuv, I installed it with the new website look.
Here is the script for enabling CommentLuv there are still a few features that need to be added.
Once I'm done I'll upload all the code changes with instructions on how to implement the new code
var commentLuv = {
enabled: true,
message: "CommentLuv enabled",
link: "<!--commentLuvStart--><p class=\"commentLuv\"><abbr><em>{0}'s last blog post.. <a href=\"{1}\" target=\"_blank\">{2}</a></em></abbr></p>",
//link: "<!--commentLuvStart--><br/><br/>{0}'s last blog post.. <a href=\"{1}\" target=\"_blank\">{2}</a>",
init: function() {
try {
var websiteBox = BlogEngine.comments.websiteBox;
if (websiteBox == null) return;
// attach UI elements: checkbox and label
commentLuv.appendElements();
// keep ref for old addComment to be used later
BlogEngine.addComment_Old = BlogEngine.addComment;
// create a new addComment function that support commentLuv
BlogEngine.addComment = function(preview) {
// if no data was found or commentluv is disabled by the user exit, use addComment_Old and exit
if (commentLuv.data == null || !commentLuv.enabled) {
BlogEngine.addComment_Old(preview);
return;
};
// check for html injection
